当我点击子窗口外部时如何关闭子窗口？
最佳答案
如果您使用默认的silverlight子窗口样式，当它打开时，外面的部分(透明的灰色部分)实际上是子窗口样式内的Grid(称为Overlay)。
所以你需要做的是处理它的MouseLeftButtonDown事件，
<Grid x:Name="Overlay" Background="{TemplateBinding OverlayBrush}" HorizontalAlignment="Stretch" Margin="0" Opacity="{TemplateBinding OverlayOpacity}" VerticalAlignment="Top" MouseLeftButtonDown="Overlay_MouseLeftButtonDown"/>
在后面的代码中，你会这样做
private void Overlay_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
this.Close();
}
为了以防万一，我也复制了这里的样式。 :)
